Unfair Competition is an in-depth investigation of the commercial activities of nonprofit organizations. Nonprofits have been granted many special privileges by the government, including exemption from taxation and subsidized postal rates. These privileges lower operating costs so nonprofits may carry out their public service mission more efficiently. The authors argue that the special privileges nonprofits enjoy give them an unfair advantage over for-profit firms, and they propose a solution to this escalating problem which has serious economic implications.
